The API of the payment system or delivery system fails and the order is not processed. The client goes to competitors.
Overloaded frontend
Heavy pages! lots of images and telegram number list unoptimized scripts make the site slow. As a result! users do not wait for the loading and close the page.
For online businesses! website accessibility issues have serious consequences! such as losing customers. If a page takes a long time to load or displays 500! 502! or 504 errors! customers will abandon the site and turn to competitors. This will lead to losses during peak seasons and SEO problems in the long term.
What is RPS and why is it important?
The main indicator to pay challenges and limitations safe attention to when overloaded is RPS ! that is! the number of requests per second that the server can process. If this indicator is too low! then users are experiencing slow response or errors.
Let’s take a closer look. For example! an online store has 1000 online visitors! each of whom makes 5 requests per minute (opening pages! adding to cart)! then the average RPS = (1000 * 5) / 60 ≈ 83 RPS.
If the server can handle 100 RPS! there buy lead are no problems. But if the load increases to 500 RPS during a sale! the site will start to slow down! and in the worst case! the server will stop responding. To avoid overloads! increase RPS.
Methods to increase RPS
The performance of an online store depends on the number of requests. Let’s take a closer look at three methods for increasing RPS.
- Horizontal scaling
When one server can’t handle the load! the simplest solution is to add more servers and distribute requests between them. To do this! we use load balancers (e.g. Nginx! HAProxy)! which evenly distribute traffic to available servers. If one server fails! the others continue to work! ensuring fault tolerance.
